You are a Product Growth Analyst at a large knowledge-sharing platform evaluating a new mobile feature for the Quora answer composer: after a user reads a question for at least 20 seconds, the app may show an AI-assisted prompt that suggests a draft outline and 3 talking points to help them write an answer faster. Today, the platform has 42 million monthly active users, 9 million weekly active users, and 1.8 million weekly answerers; only 11% of weekly readers who tap into the composer actually publish an answer, and new answerer 8-week retention is 24%. Leadership believes the feature could increase answer supply in under-served topics and improve downstream reader engagement, but it also risks lowering answer quality or cannibalizing organic writing behavior. Engineering estimates a 10-week build, and the team needs a credible prelaunch estimate to decide whether to prioritize it over feed ranking improvements.
How would you estimate the impact of this feature before launch, and would you recommend moving forward given the information available?
